| titleOfInvention | Improved process for producing pentenenitriles |
| abstract | The invention provides methods useful in the industrial scale process for hydrocyanation of butadiene to adiponitrile for recycle of unwanted byproduct 2-methyl-3-butenenitrile (2M3BN) by conversion to process intermediate pentenenitrile. The invention provides a process for generating catalysts useful for carrying out the hydrocyanation of butadiene to adiponitrile, the process comprising contacting the 2M3BN and a solution of a nickel-ligand catalyst in cis-2-pentenenitrile (cis-2PN), trans-2-pentenenitrile (trans-2PN), or a mixture thereof. The improved methods of the invention can provide improved catalyst solubility for bidentate ligands without a requirement for a Lewis acid catalyst promoter such as zinc chloride to be present. |
